    '85 50HP 2-Stroke - runs poor with wrap-around cowl on

    I went out again and figured it out. Definitely a plug wire. Putting the cowling on just the back a little made it cut out, so it couldn't be an air/exhaust issue. I pushed a plug wire and got zapped big time! Thanks for all the help guys. Really appreciate it.

    '85 50HP 2-Stroke - runs poor with wrap-around cowl on

    Hi All - Finally (with your help) seem to have my motor running like a beast, but only with the wrap-around cowling off. I'm running 5500RPM at WOT with it off, 4000RPM WOT with it on. Pretty obvious there's an air issue. Is it possible there is an exhaust leak causing dirty air? I've read...

    '85 Merc 50HP 2-Stroke - Rich/Lean Adjustment

    Thanks All - I changed out both fuel pumps, recleaned the carbs, and properly adjusted the fuel/air ratio running it on the river, in gear (son steering), per the service manual.

    '85 Merc 50HP 2-Stroke - Rich/Lean Adjustment

    Thanks!!! Really appreciate that. I've been doing the adjustments hooked to the muffs, not in gear. Can I remove the prop and put it in a tub so I'm getting back-pressure?

    '85 Merc 50HP 2-Stroke - Rich/Lean Adjustment

    Carbs were both cleaned last month. I changed the fuel pump, etc, and gaskets on the top carb, doing the bottom this week, but all of the plugs look the same. The plugs are NGK BUHW. Book says it should be BUHW-2, but I've also tried the replacement Champion L78V. All are flat like that...

    '85 Merc 50HP 2-Stroke - Rich/Lean Adjustment

    I bought and downloaded what should be a Service Manual. Looks like Clockwise is Leaner. Any confirmations would be appreciated! Thanks!

    '85 Merc 50HP 2-Stroke - Rich/Lean Adjustment

    On the adjustment screw - does turning it to the right make it rich or lean? I've been trying to tune my carbs for a little while. My plugs still seem a bit wet and I'm getting some stuttering. Overall, I'm running a million times better than before, but I want to get rid of the stutter/misses...

    '85 50HP 2-Stroke - Does not run in water

    I've got a new impeller coming tomorrow. I probably should have changed that right off the bat. Looks like I definitely need a carb adjustment though. Top 2 cylinders are wicked lean.

    '85 50HP 2-Stroke - Does not run in water

    Looks like the top 2 cylinders are running REALLY lean. Left to right is top cylinder to bottom.

    '85 50HP 2-Stroke - Does not run in water

    I'll check the spark asap. Would a fuel issue cause it to overheat? Sorry, I'm new to outboards! Whole different beast!

    '85 50HP 2-Stroke - Does not run in water

    Hi All - I have an '85 Mercury 50HP 2-stroke on my '16' Alumacraft. The motor runs fine when not in the water. I hooked up the ear muffs and ran it for about 5 minutes. No overheating, revving great, idles super smooth, etc. When I put the boat in the water, I go about 20 yards and then it...
